This utility service road heads west and down into Trancas Canyon from Zuma Ridge Motorway. It is a fairly steep route that is maintained as a road until you reach a major washout. After that point, the former road is now a trail until it deadends at an SCE tower. As the trail winds down the mountainside, enjoy a feeling of immersion in the deep canyon. Be prepared for a steady climb back up to Zuma Ridge Motorway.
From PCH, turn inland at the light at Busch Drive, across from Zuma Beach. Travel to the top of Busch Drive to reach Zuma Ridge Trailhead (aka Busch Trailhead). Hike 2.5 mi. north on Zuma Ridge Motorway to reach the Trancas Edison Road.
